JBoss Developer Framework The JBoss JDF project shows Java EE developers how to build state-of-the-art applications using the JBoss implementations of the Java EE stack. Specifically, the JDF View Frameworks section identifies a number of alternative approaches one can take when developing the view layer of your application. We in the RichFaces project have been working towards better supporting this effort by redesigning our JSF component architecture to allow the javascript part of our components (what we call our “widgets”) to be used independent of JSF, either in a standalone manner or coupled with another web framework.
